GL1500 Radiator

Post by GlassDC2B » Sat Aug 11, 2018 10:28 am



So I was riding down the road and came up behind a truck that had debris flying off , Was able to dodge most and then realized that I had a hole in my radiator. I Pulled over was able to do a quick fix and I headed home. Decided to go ahead and order a new set of radiators. When they arrived I removed the old ones and also found that I had a small leak on the a 4 way plastic hose connector that sat roughly to the from right side of the motor ( From the seated view ). So I ended up order that part as well. When the part arrived I went to install it. I realized that the NEW radiator did not have the small connector at the bottom that would go on to attach to the the Four way ( Honda Part number - JOINT, FOUR-WAY 19519-MT8-000 ). I researched this part on ebay but what comes up is a three way by the same #. I looked at the parts catalog on Cheap Cycle parts ( https://www.cheapcycleparts.com/oempart ... water-pipe ) and found that their is a 3 way valve and their is a 4 way valve.

So my question is with this new radiator that does not have a bottom nipple to connect to the 4 way. Should I purchase the 3 way valve. My worry is that the fluid is drawn from the bottom nipple or will it be fine to just install the 3 way and ignore the lack of a bottom line. I have attached the pictures of the parts in question. The first picture is an example of my old radiator to the left of the main connection at the top of the picture you can see that nipple that is not on the second picture. The 3rd is the 3 way valve that comes up on Ebay with the same part number as the 4 way valve and the fourth shows the picture of the 4 way valve that I ordered. The link above is the schematic that I was referencing.

Any help would be great,

Thanks in Advance

The 88-91 GW used a different coolant hose routing as you have found out with an incorrect right radiator. Bite the bullet and bring to a radiator repair shop to install a hose fitting for new radiator, you do not want to just disregard this coolant hose as it is the by-pass. Later years were water pump mounted.

Thanks for the response....

So here is a carry-on question a friend of mine was just looking at my bike and mentioned that he had purchased a parts box off eBay awhile back. He in fact showed me a Water pump cap that had 2 nipples on it, Do you think that I could attach one of the 2 nipples to the 4 way valve ? Granted their would be 1 nipple open that I assume I could just go ahead and cap or finagle a way to seal it off.

Is your original radiator not repairable by a competent radiator shop?
They say 98% of all Hardleys ever made are still on the road..... The other 2% made it home. :lol:
(I stole this from somebody on another GW site...) :roll:
